This line chart visualizes hourly temperature readings from the Data Canvas Sense Your City Dataset, emphasizing the curve’s continuous form with a smooth natural spline and no individual data points. The React-based application uses d3.scaleTime and d3.scaleLinear to map timestamps and temperatures, while d3.line with curveNatural generates the stylized path. It renders as SVG with shared axis components, and the visualization omits circles in the marks layer to focus purely on the temperature trend across the week.
